Ultramarine Blue plots cooler and bluer than the more saturated French Ultramarine.

Temperature aside, both blues have equal permanence, light fastness and semi-transparency. Ultramarine Blue is slightly less granular in concentrated washes. For less saturation, sedimentation and cost, use Ultramarine Blue straight, for vibrant crayon-like colour or mixed with a cool red for dark, effective neutrals.

• Light fastness: Excellent
